问题描述

前提 : 自定义UICollectionViewFlowLayout:包含若干个UIScroll
理想现象 : 正常相应
报错reason :

2016-04-12 19:17:59.919 weather[95267:1467874] the behavior of the UICollectionViewFlowLayout is not defined because:2016-04-12 19:17:59.920 weather[95267:1467874] the item height must be less than the height of the UICollectionView minus the section insets top and bottom values, minus the content insets top and bottom values.

解决方式 : 添加以下设置

self.automaticallyAdjustsScrollViewInsets = NO;

分析:

1.automaticallyAdjustsScrollViewInsets根据按所在界面的status bar，navigationbar，与tabbar的高度，自动调整scrollview的 inset,
2.设置为no，不让viewController调整，布局自定义

修改方法:

- (void)viewDidLoad{    self.automaticallyAdjustsScrollViewInsets = NO;    [self.collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:ID];}
